IMPROVEMENT IN HARVES'l'ER-SEATS.

Specification forming part of Letters Patent No. 1 63,287, dated May 11,1875; application filed April 1, 1875.

To all whom it may concern Be it known that we, GYRENUs WHEELER, Jr.,and HENRY J. CASE, both of Auburn, county of Cayuga, State of New York,have invented a new and useful Improvement in Seats for Harvesters, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawing, making part of thisspecification, in which- Figure 1 is a perspective view of our improvedharvester-seat, showing the seat in full line in one position and indotted lines in another. Fig. 2 is a side view of the same. Fig.3 is asection through the seat and seatstandard; and Fig. 4. is a plan or topview of the notched disk, to which the seat-standard is connected.

The invention relates to a novel means for adjusting the seats ofharvesting-machines, whereby the same can be turned to any desiredposition or angle on the frame, while at the same time its support shallalways remain stationary upon the frame when in use 5 and consists inconnecting the seatspring to a notched disk or plate, which is held by,but free to turn in, a hollow disk or plate secured to the frame, and inthe combination, with said notched disk or plate, of a spring bolt orpin for holding the notched disk at any desired point of adjustment, ashereinafter described.

In the accompanying drawings, A represents a section of the frame, uponwhich is mounted the socket-plate B, in which the footplate of the seatspring or support is mounted, and in which it is free to turn. Thesocketplate B is made in the form of an inverted cup, and is providedwith a circular opening in its top, and has formed upon its outer rim oredge lugs or cars I), by which it is secured to the frame. This plate isalso provided with an extension or projection, b, in which is placed apin or bolt, b the handle of which, b passes up through an l -shapedslot cut in said protion I) and behind said bolt is placed a spring, I),as shown in Fig. 3 5 this bolt, when the plate B is placed over thefoot-plate hereinafter described, springing into notches formed thereinfor holding said plate at any desired point. The foot-plate C is of adiameter to fit the circular opening in the plate B; but has formed uponits lower portion a series of teeth or projections, c, which areinclosed by the socket-plate B. This foot-plate has also formed with orotherwise connected with it a curved standard, 0 to which theseat-spring C is connected by means of a screw, 0, the lower end of saidspring fitting into a groove or recess formed in the face of the plateC. The spring or seat support is extended up to the usual height, at anangle'of about forty-five degrees, to the seat'plank, where it is turnedor bent at an angle, bringing it parallel with the face of said plank,and upon this extension of the spring the seat is connected. D is arose-plate, which is provided upon its lower face and at two sides withoverhanging lips d, which clasp the edge of the spring, and to thisplate the seat D is connected, being provided upon its lever-face withnotches matching those in plate D, and both being connected with thespring by a through-bolt, D and thumb-nut D The extension of theseatspring is provided with a series of perforations, by means of whichthe seat can be set V at any desired point in its length.

The seat, as represented in full lines, Fig. 1, is in the position whichit generally occupics on a mower, and when it is desired to change theposition of the seat when the machine is converted into a reaper, orfrom any other cause, the bolt b is drawn back,and the handle caught inthe slot b which leaves the disk C free to turn in the disk B. When thedisk 0 is turned to the desired angle, the bolt is released, when itsprings into one of the series of notches formed between the teeth inthe disk 0, which firmly hold the seat-support in that position.

If it is also desired to change the angle of the seat to its support,the nut D is loosened, and plates D and D drawn apart, when the seat canbe turned to the position shown in dotted lines, Fig. 1, when the nut 1Bis tight- In testimony whereof we have hereunto set our hands this 23dday of March, A. D. 1875.
